Identification of Magmatic Fluid Inputs and Geochemical Evidence of the Mantle-Derived Components in Magma-Heated Geothermal Systems

Energies
Magma-heated geothermal systems have garnered significant attention in academia due to their unique formation mechanisms and vast potential. This paper focuses on the Rehai, Ruidian, and Banglazhang geothermal fields in the Tengchong area. We present the

Petrogenesis of Heavy Rare Earth Element Enriched Rhyolite: Source and Magmatic Evolution of the Round Top Laccolith, Trans-Pecos, Texas

, 2018
The Round Top rhyolite located in Trans-Pecos Texas is enriched in Be, F, Li, Nb, Rb, Sn, Th, U, Y, Zr, and rare earth elements (REEs). REE-bearing minerals are mainly ubiquitous nano-scale accessory phases throughout the groundmass, incorporated in ...

Imaging Magma Reservoirs From Space With Altimetry‐Derived Gravity Data

AGU Advances
I investigate the detectability of magma reservoirs in the vertical gravity gradient (VGG) anomalies calculated from satellite altimetry data. First, I calculate a suite of synthetic seamount models to show the expected VGG anomaly characteristic ...

Coupled hydrothermal venting and hydrocarbon seepage discovered at Conical Seamount, Papua New Guinea

Scientific Reports
During research expedition SO299 with the German RV Sonne, we discovered the first deep-sea hydrothermal vent system along the Tabar-Lihir-Tanga-Feni island chain in northeastern Papua New Guinea.

Segmented dike intrusion linked to multi-level magma storage during and before the 2025 eruption at Erta Ale (East Africa)

Frontiers in Earth Science
IntroductionDike intrusions can assist continental rifting and plate divergence. However, our understanding of the magma dynamics during diking and the architecture of the magma storage that feeds dikes are still limited by temporally and spatially ...

Sulphur behaviour in Etnean magmatic system (Italy

, 2015
Sulfur is an essential volatile component of basaltic magmas and it is mostly dissolved as S6+ and/or S2- depending on the redox conditions. Mt. Etna continuously discharges enormous quantity of SO2 (~3563 t/d [1]).

Deep crustal hot zones control shallow magma reservoirs in an active transcrustal magmatic system

Communications Earth & Environment
Understanding volcanic dynamics and assessing eruptive risk require examining the entire transcrustal magmatic system. However, direct imaging of magma distribution and connectivity from the Moho to the surface remains rare. Changbaishan-Tianchi volcano,

Genetic geological model of diamond-bearing fluid magmatic system

Записки Горного института
The article proposes a genetic geological model of diamond deposit formation associated with kimberlites and lamproites. It is based on the synthesis of published data on diamond-bearing kimberlite systems and an original study of the ontogenetic ...
